I always wondered, about the reasons which made Pelikan pens so famous. Although, I have to admit I never used any Pelikan pen before. A few days ago, I saw an ad for an old Pelikan pen in the second-hand marketplace, so I took a gamble and purchased this Pelikan 400NN. It was a remote transactionss so I was not sure what was the condition of the pen. Images did not show any significant damage. I bought this pen for 70USD. Today I received the pen and as expected piston was almost jammed. With extra care, I could turn it. But luck was on my side, and when I tried to unscrew the nib section, the section opened without any resistence. The pen was clean. I flushed it with clear water. I applied silicone grease on the piston and piston started to move like new. After assembling it back, I filled it with Waterman Inspired Blue. The pen writes beautifully. Now I understand why some people were crazy about these vintage nibs. The nib is smooth, and with a flex, I have not experienced with any other pen.
This is not a review just sharing my experience with my first Pelikan although a vintage. Below are some of the images. Hey! I forgot the important part. The pen came in original box with matching Mechanical Pencil and Ballpoint.
